120+25x=45x
Step 1: Simplify both sides of the equation.
25x+120=45x
Step 2: Subtract 45x from both sides.
25x+120−45x=45x−45x
−20x+120=0
Step 3: Subtract 120 from both sides.
−20x+120−120=0−120
−20x=−120
Step 4: Divide both sides by -20.
−20x
−20
=
−120

Answer: The increase in the percent of household with cable television = 45.5%.
Step-by-step explanation:
Given : The percentage of households in the u.S. With cable television increased from 22.5% in 1980 to 68% in 2000.
i.e. Previous percentage in 1980 = 22.5%
New percentage in 2000= 68%
Now , the increase in percentage = (New percentage) - ( Previous percentage )
= 68% - 22.5%
= 45.5%
Hence, the increase in the percent of household with cable television = 45.5%.
Answer:
$64,000
Step-by-step explanation:
Friday, 45 / 9 = 5
So the investment will double 5 times
First time
2,000 (starting investment) × 2 = 4000
Second time
4000 × 2 = 8000
Third time
8000 × 2 = 16000
Fourth time
16000 × 2 = 32000
Fifth and final time
32000 × 2 = 64000
$64,000
We know that 8(hrs) is 4 times 2(hrs) so now we just need to multiply.
Multiply 1,100 by 4.
1,100 × 4 = 4,400
The jet will fly 4,400 miles in 8 hours.
The GCF of 3x^4 +18x is 3x. 3x^4 and 18x can both be divided by 3x. 3x(x^3+6)
